NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Application filed May 15, 1915. Serial No. 28,394.

To all whom it may concern:

Be it known that I, SAMUEL F. LEAGER, a citizen of the United States,residing at Spotswood, in the county of Middlesex and State of NewJersey, have invented a new and useful Non-Refillable Bottle; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to an improved non-refillable bottle, and anobject of the invention is to provide a device of this nature,comprising simple, eflicient and practical features of constructioncomprising a stopper and suitable valve mechanism in the stopper toprevent the refilling of the bottle.

In practical fields the details of construction may necessitatealterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a vertical the neck of a bottle, showingthe improved stopper and valve mechanism in section, for preventing therefilling of the bottle. Fig. 2 is a vertical sectional view through theneck of the bottle, showing the neck inverted, and the position of oneof the valves as the fluid is leaving the bottle. Fig. 8 is a viewsimilar to Fig. 2, showing the position of one of the valves, when anattempt is made to fill the bottle with fluid under pressure. Fig. 4 isa sectional view on line 4-4: of Fig. 1. Fig. 5 is a sectional view online 5-5 of Fig. 1.

Referring to the drawings, 1 designates the portion of the body havingthe usual neck :2, which receives the glass stopper 8, the contractedportion 4 of which has a cork band 5 surrounding the same, which fitsbetween the contracted portion and the inner wall of the neck. Thereduced or contracted portion of the stopper 3 has a cylindrical recessor bore 6 extending partially transversely, in which recess or bore acylindrical pin 7 is seated, there being a coil spring 8 interposedbetween the pin and the inner end 9 of said recess, so as to hold thepin in the recess 10 of the inner face or wall of the neck of thebottle. When inserting the stopper the pin 7 is held depressed againstthe action of the spring 8, and just so soon as the reduced orcontracted portion of the stopper enters the neck 2 sufficiently tocause the recesses (S and 10 to register, the pin 7 will be thrown inengagement with the recess 10, thereby the removal of the stopper. Thelower portion of the reduced part of the stopper is provided with acylindrical chamber 11, and fitting the extreme lower portion of thechamber and provided with a glazed joint at 12 with the chamber is aglass disk 13 provided with an opening 1 1. The enlarged portion 15 ofthe stopper has a passage or opening 16 extending vertically, and alaterally or horizontally extending passage 17, which merges into asecond vertical passage or opening 18. These passages 16, 17 and 18 arearranged, as will be noted, to form a continuous passage, but angular,owing to the transverse portion 17, thereby preventing an instrument,wire or the like from being inserted sufiiciently into the chamber 11,in order to manipulate the valve member so that the bottle could berefilled. The upper wall of the chamber 11 is dished or provided with adepression 19, to receive the glass ball weight 20 when the bottle isinverted. A glass disk constituting a valve 21 is arranged in thechamber 11, so as to cover the opening 14, and secured to the glass diskvalve 21 by means of the wedge shaped projection or lug 23 is a corkdisk 2 1, on which the glass ball weight 20 engages. The adjacentengaging surfaces of the disk valve 21 and the disk 13 are groundsuitably so as to firmly and squarely engage, and in case any fluid thatmay accumulate on the engaging surface of the disk 13 will cause theglass disk valve 21 to seal tighter. When inverting the bottle as shownin Fig. 2, to empty the contents or a portion thereof from the bottle,the glass ball valve seats in the depression or dish portion 19 of thetop wall of the chamber 11, whereas the cork disk with the glass diskvalve 21 rests upon the ball, the pressure of the fluid in the bottlewhen inverted acting to unseat the disk valve 2l,'thereby permitting thefluid of the bottle topass out through the passages 16, 17 and 18.However, when an attempt is made to refill the bottle, by inverting thesame and forcing fluid under pressure thereinto, the fluid will act toforce against Patented Feb. 23, 1916.
